IMPROVEMENT IN, HORSE-POWERS.

Specification forming part of Letters Patent No. 152,166, dated .lune 16, 1874; application filed May 23, 1874.

Tov all 'whom 'it may concer-n:

Beit known that I, ANDREW J. PIERCE, of Cherryvale, in the county of Montgomery and State of Kansas, have invented a new and useful Improvement in Horse-Power, of which the following is a speciiication:

Figure l is a vertical cross-section of my improved horse-power, taken through the line a' a', Fig. 2. Fig. 2 is a top view of the same.

Similar letters of reference indicate correspondin g parts.

My invention has for its object to furnish an improved horse-power, which shall be simple in construction and convenient in use, being so constructed that it can be conveniently taken down, set up, and carried from place to place, and which shall be strong, durable, and not liable to get out of order, and will allow as many horses to be attached to it as the work to be done may require.

The invention consists in the pulley-frame, made in sections, and provided with supporting-plates at their joints; in the combination of the center block, the radial sills, and the triangular adjustable frames, with the pulleyframes and pulleys; in the combination of the spur-wheel, the shaft, the gear-wheels, and the frame, with the tumbling-rod, the endless chain, and the sectional pulley-frame, as hereinafter fully described.

Arepresent-s a polygonal center block, which is staked or otherwise secured to the ground, and in the lower part of the sides ot' which are formed mortices or notches to receive the inner ends of the radial sills B, the outer ends of which are provided with loops b", or other appliances, to enable them to be conveniently secured in place by stakes. G are `metallic frames, made in the form of right-angled triangles, the base bars of which are made iiat, and are slotted longitudinally to receive the bolts by which the said frames are secured to the sills B, so that by loosening the said bolts the frames C may be moved from or toward the center to tighten or slacken the endless cha-in. The upper part of the vertical bars of the frames C project above the upper ends of the inclined bars of .said frames to serve as journals for the pulleys for the endless chain, and as posts to support the sections of the pulley-frame.v D are the sections of the pulleyframe, any desired number of which may be used, and each of which consists of a top and bottom bar, connected by one or more short studs, d. The ends of the top and bottom bars are beveled or inclined so that the seetions may meet at an angle, and fit upon each other, and are notched to receive the projecting upper part of the vertical bars of the frame C. The adjacent ends of the sections D rest upon plates E, placed upon the projecting upper part of the vertical bars of the frames C, and which have their outer and inner side edges bent upward or flanged to iit upon the side edges ofthe adjacent ends ot' the bottom bars ot' the sections D. Similar plates may be placed above the ends of the sections D, and secured by keys passed through holes in the upper ends ofthe vertical bars of the frames D, ifdesired. F are flanged pulleys, one ot' which is placed upon the projecting upper end of the vertical bar of each ofthe frames C, between the ends of the top and bottom bars ot' two adjacent sections, D. To, and between the top and bottoni bars of each section D are pivoted one or more ot' the pulleys F. G is an endless cha-in, which passes around the pulleys F, and is kept in place upon them by their ilan ges. The links ofthe chain G are so formed as to receive and tit upon the spurs of the spur-wheel H, attached to the vertical shaft I, the journals of which revolve in bearings in the top and bottom bars of theframe J, by which a portion of the pulley-frame D is replaced, and the base otA which is securely staked to the ground. To the sides of the upper end ofthe frame J are attached brackets, to which the ends ofthe adjacent sections D are detachably secure( by pins. The frame J is strengthened against inward draft by a brace, K. To the lower part of the vertical shaft I is attached a large bevel-gear wheel, L, the teeth ot' which mesh into the teeth of the small bevel-gear wheel M, attached to or formed upon the tumbling-rod N, which revolves in bearings in the base ofthe frame J, and from which mot-ion is taken to the machinery to be driven. O are the draw-rods, the rear ends of which are attached to the endless chain G, and the forward ends oi' which are provided with loops, rings, or hooks for the convenient attachment ot' the draft. The

forward parts of the draw-rods O are connected with the chain G by short rods o to prevent them from dropping down, and to keep the point of draft attachment at the proper distance from the chain Gr.

The upright frames C may be strengthened against lateral irovement by inclined braces extending from the upper part of each frame to the lower part of the next Frames. These braces are not shown in the drawings.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The pulley-frame, made in sections D, and provided with supporting-plates E at their joints, substantially as herein shown and described.

2. The combination ot' the center-block A, the radial sills B, and the triangular adjustable frames C, with the pulley-frames D and pulleys F, substantially as herein shown and described.

3. The combination ofthe spur-wheel H, shaft I, gear-wheelsL M, and frame J, with the tumbling-rod N, endless chain G, and sectional pulley-frame D, substantially as herein shown and described.
